I have the below output with finger tips detected and the points are pushed into the vector. The below is the output I got and blue points are the information I have. With these information can I crop the finger part alone? If so can you please provide your suggestions.

Output I got and points information:

Area to be cropped is marked in red:

would that work if you connect blue 2 and blue 3, blue 3 and blue 4? That will segment the middle 2 fingers. Then draw a line passing blue 4 and parallel with the green line passing blue 5, and another line passing blue 3 parallel with the green line passing blue 3

  • But these numberings are not same always. It depends on the convexity defects found. – user2727765 Dec 24 '13 at 17:51
  • Yes. But in most cases it is feasible if you already succeeded in the corner detection (tip on the fingers, and connections between fingers). – lennon310 Dec 24 '13 at 17:53
